Over lobectomie en pneumonectomie wegens longtuberculose
In de inleiding wordt het doel van deze studie geformuleerd als een poging tot bundeling van de snel groeiende ervaring van de behandeling der longtuberculose door middel van pneumonectomie, lobectomie of segmentale resectie. In het eerste hoofstuk worden eerst enkele principes besproken van de tuberculosebehandeling in het algemeen en van de longtuberculose in het bijzonder. Zie: Sameenvattin
Nonnormative Ethics: The dynamic of trans formation
In this thesis I propose to address trans as nonnormative ethical formation. In
the current definition (Stryker, 2008) trans is defined as a movement outside of
constraints that encapsulate normative genders. Preciado (2012) argues that
trans involves the constitution of a soma-political project, beyond identity.
As opposed to theories that describe identity formation as aspirational, the
thesis extends Aristotle’s arguments for ethical formation in terms of interactive
engagement within environments through an agents’ dunamis – the powers of its
Soul (Lee 1992). The limits of the Aristotelian model will be overcome by use of
Anzaldúa (1987) and Lugones (2003). The navigation away from imposed
normative environments through agential action will be shown to lead to
nonnormative logos: a formational logic shaping perception, action, and practical
reflection culminating in practical truth. This reading enables centering
somatechnical processes (Sullivan 2009) as generative of forms of life.
Wittgenstein suggests that agential logic informs forms of life, shaping validity of
both principles and decisions. I use this insight to claim that the polis is ordered
by a single logic that informs norms. I propose nonnormative ethics to
encompass agents with differing logos. Reading eudaimonia as the demon
standing behind the agent, I will suggest that nonnormative ethics takes place
outside of the polis on the ‘demonic grounds’ (McKittrick 2015, Wynter 1990).
Nonnormative ethical connections are multilogical and are bridged by collective
codes.
I will draw from Glissant (2002) to make a case for acknowledging agential
opacity away from a pathologising claim to interiority. I will argue for nonantagonistic
playfulness and loss (Lugones, 2003) as keys to the emergence of
nonnormative codes enabling shared forms of life. I propose that the distinction
with the codes of the polis is the willingness to share loss, instead of exploitation.
The thesis makes the case that bodily change is central to changing one’s
understanding of, and relation to one’s surroundings. Furthermore, I argue such
change is a collective process, and that emerging epistemologies are connected
to contextual ethics
The significance of electro-encephalogarphy for the dianose and localisation of cerebral tumours
Field Emission for resonance sensing in MEMS/NEMS
In the past decades, there is a considerable interest in the sensor community to move from micron to nano-devices, typically scaling of resonators such as cantilever beams
Diffusion of silver during sintering in high permittivity COG dielectrics
To achieve cost reduction in multi-layer ceramic capacitors and actuators, which use a silver-palladium alloy as internal electrode, the trend is to use alloys with the highest silver content possible. This requires ceramic materials which must be sintered at a relative low temperature. Goal is to avoid much diffusion of silver into the ceramics. Analysis of the composition of the electrode in multilayer components is a good tool to investigate the diffusion of silver during sintering. Analysis of various multi-layer components with different silver-palladium alloys shows that the diffusion of silver during sintering is dependent on the difference between the sintering temperature of the multilayer component and the melting point of the silver-palladium alloy used. Diffusion of silver into the ceramics during sintering is negligible when this difference is at least 100° C
Progress in DNP theory and hardware
Dynamic nuclear polarisation is a technique that allows one to increase the signal-to-noise ratio in an NMR experiment substantially, by transferring the inherently larger electron polarisation to the nuclei. Quantum mechanical models of this effect have thus far been limited to the description of only a few nuclei. This is due to the exponential scaling of the matrices involved in the description of the system. In this thesis methods of reducing the state space needed to accurately describe the simulation of solid effect DNP were explored and tested. Krylov Bogoliubov averaging has been used to remove high frequency oscillations from the system Hamiltonian and confine the trajectory of the dynamics to the zero quantum coherence subspace. Truncation of the basis spanning the Liouville space to low spin correlation orders has been tested and a condition for a minimum truncation level was found. A strategy based on a projection method, which allows one to describe the spin polarisation transient with multi-exponential functions, is introduced. This results in a linear scaling of the propagator with the number of spins. The influence of the parameters involved in the solid effect on the dynamics of the polarisation build up is discussed.
The second part of this thesis is concerned with a novel approach to detecting fast molecular dynamics with the use of multiple RF receive and transmit coils. A proof of principle probe with two decoupled RF coils is presented, as well as a field map based shimming strategy and fast 2D data acquired with the probe. Lastly a probe with six RF coils, based on the design of the dual coil probe, will be presented, and initial data shown. The potential for using this probe in hyper-polarisation experiments for protein binding and folding studies will be discussed
Comparative study of Clâ‚‚, Clâ‚‚/Oâ‚‚, and Clâ‚‚/Nâ‚‚ inductively coupled plasma processes for etching of high-aspect-ratio photonic-crystal holes in InP
An extensive investigation has been performed on inductively coupled plasmaetching of InP. An important motivation for this work is the fabrication of high-aspect-ratio holes for photonic crystals. The essential chemistry is based on Clâ‚‚ with the addition of Nâ‚‚ or Oâ‚‚ for sidewall passivation. The influence of different process parameters such as gas flows, temperature,pressure, ion energy, and inductively coupled plasma power on the hole geometry is presented. It is concluded that photonic crystals can be etched with Clâ‚‚ only; however, temperature and pressure control is critical. Adding passivation gases largely broadens the window in the parameter space for hole etching. Most importantly, etching of narrow holes can be carried out at higher temperatures where the etching is mass limited and spontaneous etching of InP by Clâ‚‚ occurs.Part of this research is supported by NanoNed, a technology program of the Dutch
